The league hasn't had a top-10 pick since Michigan's Jake Long and Ohio State's Vernon Gholston went No. 1 and No. 6, respectively, in the 2008 draft. The Big Ten narrowly avoided being shut out of the first round for the first time since the NFL-AFL merger when Wisconsin's Travis Frederick went at No. 31 in April's draft.

Is the troubling trend for the Big Ten more of a coaching/development issue or a recruiting issue? The declining number of first-round picks might have more to do with the Big Ten footprint than the Big Ten Conference.

As CoachingSearch.com's Chris Vannini points out, certain states in the Big Ten footprint, namely Ohio, have seen a drop in producing first-round picks in recent years. Vannini looked at where first-round picks from the past eight drafts played their high school ball.

Not surprisingly, Texas (17) and Florida (12) produced the most first-round picks between 2010-13, followed by Georgia (10) and California (8). Florida, Texas and California also were among the top producers in the previous four drafts (2006-09).

Pennsylvania is the top producer in the Big Ten footprint with five first-round picks since 2010. Michigan (4) and Wisconsin (4) are next, along with future Big Ten state New Jersey (4).

Where's Ohio? Way down the list with just two first-round picks since 2010. It comes as a surprise as Ohio is celebrated for its high school football and serves as the starting point in recruiting for many Big Ten programs.

Ohio produced nine first-round draft picks between 2006-09. New Jersey also saw its total drop from 10 (between 2006-09) to four (between 2010-13).

Pennsylvania and Wisconsin both produced three more first-round picks in the past four drafts than the previous four. All four Wisconsin products -- J.J. Watt, Gabe Carimi, Kevin Zeitler and Frederick -- played for the Wisconsin Badgers during their run of Rose Bowls. Michigan saw a slight increase in recent years, Illinois held steady and Indiana dropped from four (2006-09) to two (2010-13). Minnesota had one first-round pick in 2012 after none from 2006-09, while Nebraska and Iowa aren't on the board for either span.

What about the Big Ten's other new territory, the Washington D.C./Maryland/Northern Virginia region? Maryland's total dropped from four (2006-09) to three (2010-13), Virginia's went from seven (2006-09) to three (2010-13) and Washington D.C. failed to produce a first-round pick from 2010-13 after having two between 2006-09.

What does this mean for the Big Ten? First-round draft picks are only one way to gauge the strength of a league or a region, but the numbers reinforce that much of the nation's elite talent grows up far from Big Ten campuses. Big Ten schools have to spread their wings in recruiting and invest more time and resources in states like Texas, Florida and Georgia. Many programs already do this, but there's a greater sense of urgency.

The Ohio total is a bit alarming, but I'd be surprised if the state produces so few first-round picks in the next four years. It will be interesting to see what happens with the Wisconsin total under a new Badgers coaching staff.

I still like the Big Ten's new additions, Rutgers and Maryland, from a recruiting standpoint, but the declining totals of first-round draft picks from both areas are a bit unsettling as the two programs prepare to move to the Big Ten in 2014.
